1979 Yamaha MX100 Service and Repair Manual

Yamaha covered the 1979 MX100, model code MX100F, in part number LIT-11616-DT-MX, a volume that also documents the MX175 of the same year.

Pairing the two machines was sensible for a service department. The shared work appears once, and where the MX100 differs from its larger sibling the text says so. Coverage stays within the 1979 model year, so nothing here has been carried forward or revised for a later season.

The information is what factory service documentation provides: the order for stripping and rebuilding assemblies, torque values for fasteners, clearances and adjustment settings given as measurements, wiring diagrams for the electrical circuits, and troubleshooting that works from a symptom toward its cause.

Find the MX100F code on your machine and confirm it before using a figure from LIT-11616-DT-MX on it.
